The surname JACKISON in Australia/New Zealand is not a name in common use by anyone except Francis and his family. He has either made it up or it is a variation on another name, possibly Nordic?
Does the certificate have original signatures? Did he sign confidently?
I would get a printout of the second marriage to see if he gives the same information about his parents. It wasn't a long time, but if he had invented the names he might not have remembered what he said the first time. It is always good to see if someone is consistent with their information.
The death is indexed by the Registry as Arthur Albert Francis so the correction was an official one. You have cropped the document but it should have a notation of when the correction was made, probably somewhere in the margin or on the bottom.
The intention to marry as mentioned by JM should give a "length of residence" and it would be good to know how long he says he has been residing in Auckland. You can ask on the NZ board for someone to do that for you.
